LOCAL DOPPLER-PROFILE ESCAPE FACTORS WITHIN THE CYLINDER

Local escape factors for photons emitted within a Doppler (Gaussian) f requency profile, at specified radial locations within the homogenous infinite cylinder, are calculated and tabulated. They have been checke d for numerical accuracy against a previously calculated global (integ rated) escape factor. Their general behavior is illustrated in figures , which show also the expected approach of the surface escape factor t o the plane-parallel value of 1/2 as opacity increases.
